While preparing an edition containing all the works-not-by-JS-Bach from the Neumseister Sammlung, I found one work I have not yet published: Johann Michael's Bach prelude to "Auf meinen lieben Gott". I did create a score, almost a year ago, and even recorded it, yet somehow forgot to publish it. Keeping track of all the scores I produce is difficult, obviously.... I decided to record it anew, just for the pleasure of playing Johann Michael Bach again. It's one of those pieces that show how deep the musical talent runs in the Bach family.
